OSLO (AFP) - A grown moose belches out methane gas equivalent to 2,100 kilograms (4,630 pounds) of
carbon dioxide a year, contributing to global warming, Norwegian researchers said Wednesday. That is more
than twice the amount of CO2 emitted on a round-trip flight across the Atlantic Ocean from Oslo to the Chilean
capital Santiago, according to Scandinavian Airlines.

"An adult moose emits about 100 kilograms of methane gas a year. But methane gas is much stronger than
carbon dioxide, so to get the equivalent you have to multiply by 21," professor Odd Harstad at the Norwegian
University of Life Sciences told AFP. With an estimated 140,000 moose roaming Norway's forests, that is a
total of of 294,000,000 kilograms of CO2 per year.
